Página 4 - Mechanics, printed in our printing-offices, would serve for the universe. The universe, if open throughout to our explorations, would vastly expand our knowledge, and science might have a more beautiful superstructure, but its basement-laws would be the same. The earth, therefore, although but an atom in immensity, is immensity itself in its revelations of truth; and science, though gathered from one small sphere, is the deciphered law of all spheres. It is well to have the mind deeply imbued with...
Página 43 - In each elliptical circuit, therefore, the line of 68° F. should be an oblique diagonal line to the ellipse ; and thus it is in the North Atlantic, the South Atlantic, the North Pacific, the South Pacific (though less distinctly here, as the ocean is so broad), and the Indian Ocean. The torrid-temperature zones are very narrow to the eastward and broad to the westward. The temperate zones press towards the equator against western Africa and Europe, and western America.

Tigers as large again as the biggest Asiatic species lurked in the ancient thickets; elephants of nearly twice the bulk of the largest individuals that now exist in Africa or Ceylon roamed in herds ; at least two species of rhinoceros forced their way through the primaeval forest ; and the lakes and rivers were tenanted by hippopotami as bulky, and with as great tusks as those of Africa.
Página 640 - I ascertained, in 1829, some facts which throw light on the rate at which the sea gains upon the land. It was computed, when the present inn was built, in 1805, that it would require seventy years for the sea to reach the spot : the mean loss of land being calculated, from previous observations, to be somewhat less than one yard annually.

Página 721 - ... in the scheme of creation which it presents. It is both true and divine. It is a declaration of authorship, both of Creation and the Bible, on the first page of the sacred volume. There can be no real conflict between the two Books of the GREAT AUTHOR. Both are revelations made by Him to man, — the earlier telling of God-made harmonies coming up from the deep past, and rising to their height when man appeared, the later teaching man's relations to his Maker, and speaking of loftier harmonies...
Página 191 - ... the copper probably came up, having apparently been derived from copper-ores in some inferior Azoic rocks through which the liquid trap passed on its way upward. The extent to which the rock and its cavities are penetrated and filled with copper shows that the metal must have been introduced by some process before the rock had cooled.
Página 544 - Besides these," continues Professor Owen, " troops of Hyenas, larger than the fierce Hysena crocuta of south Africa, which they most resembled, crunched the bones of the carcasses relinquished by the nobler beasts of prey, and doubtless often themselves waged a war of extermination on the feebler quadrupeds.
